Otitis externa can usually be remedied with a simple course of eardrops, as prescribed by your local GP. If your symptoms linger or your case has been particularly severe, you may be referred to a specialist who may undertake, micro-suction or dry swabbing to remove earwax and other debris to make your drops more effective. Severe cases may require an earwick, a plug made from soft cotton gauze that helps insert medication into your ear.

While you take your medication, it is important to take certain steps at home to help aid your recovery. Avoid getting your ear wet by wearing a shower cap when you bathe, and gently remove any discharge by gently swabbing around your ear rather than in it. Remove any hearing aids, ear plugs and earrings will also help prevent the spread of bacteria.

If you are experiencing symptoms of otitis externa, it is important to request an appointment with your local doctor.
